[Ducati Scotty]

I keep thinking of getting an aftermarket exhaust...

and then one of the local knuckleheads rides by with a bike that shakes my house.  I like my neighbors and they like me, I'll keep it that way.  I don't think I'd even like it that loud for more than half an hour.  Plus, though the cat blues the chrome it does make the stuff from the pipe a little less nasty.  Gotta think of the future.

Not to say I won't be tempted again

All aftermarket exhausts may not be equal in terms of noise.
I was delighted by how much perkier my bike ran with the Goldie on, but a year later I'm wanting to tone it (the noise) down a bit. Apart from the sheer volume, especially in town, it's too much blat and not enough thump. It can be kind of tiring on a long ride.
I don't mind the sound of the stock exhaust, but that's all I don't mind about it!
I'm awaiting delivery of a new Indian exhaust, more classic looking on the bike, and I'm told it has the classic Bullet bass thump.  I'll let you know....
That said, even the Goldie is acceptable for slowly chugging down the road and away from the neighbours.... especially with earplugs in ...
As for the future, people been telling me for decades the future's coming. Never does....

Will what exhaust did you order?

What I really want to do is install a cutout so I can make it loud sometimes and softer others.. I looked high and low for a 1.75" cutout pipe (like this), but couldn't find one.


I was thinking that I could put some sort of valve or adjustable opening on the flanged area there and just open it up a bit when I wanted the noise..

kinda like peacemakers..

I emailed them to see if they have a single 1.75" version.. I doubt it though. Any other companies like this?!

I've ordered the Electra silencer from Enfield County in India. Should arrive any day now..

Big Al from Fresno has a Honda track bike, It looks like a vintage racer. What I noticed in his exhaust was a device I had not seen in decades. It is (was) called a Snuff-r-not. Basically it is a flapper valve in the pipe that regulates the outflow of the pipe. When fully closed, some exhaust escapes around the valve. When open it still blocks some flow. Not an ideal situation.

Remember Little Deuce Coupe? "She purrs like a kitten 'till my Lake Pipes roar"

There was an exhaust cutout for Harleys made a few years ago.

Probably the best system is a removable baffle.

Recovering from a leg injury and not able to ride for a few weeks, but today the leg feels better.  This great weather we're having is calling and I'm gong to give riding a try. With some Tylenol on board I think I can make the 150 mile round trip to see a friend.

Wash, lubed the chain, anti squeal for the front pads, new grips with safety wire.

40 years ago I removed the muffler and put a Snuff-r on my Ducati. 
I don't recall that it added much power but it sure sounded faster. 

Sense those days, Arizona has outlawed all forms of exhaust cut-outs including the ones with bolted on caps on any street legal machine.

I rode 100 miles in the summer-like Seattle weather.  Temps were in the high 60s and low 70s.  That's PERFECT for wearing full ATTGATT.

The C5 putted along fine and I have learned how to minimize the poots and pops from the upswept muffler by gently easing off the throttle and not blipping the throttle on downshifting. 

Today was a relaxing "cycle-therapy" ride on mostly 2-lane backroads averaging 45mph.  Wearing ear plugs really makes the motor seem smoother and slows down the onset of fatigue.  Keeps the tinnitus away too (I had it many years ago).

With a tank full of 89 octane "clear" gasoline (no ethanol), the motor ran fine.   It filled up back in town and showed 76mpg (US).   

On the ride the odometer went 1800 miles as I went into Duvall and Snohomish, WA.  I posted a couple of photos in the gallery.

I checked the new plug for color (another thread) and then applied anti-seize goop before reinstalling it.  The chain got lubed for the next ride.

Will, is that the same as the nfield EFI? Maybe the muffled section looks a bit shorter, hard to tell.

Old friend JC Whitney still offers a weld in remote cable exhaust cut out. Will fit 1 3/4 pipe.

Will this work.? Maybe.
The thing about Snuff-or-nots, is u have to start with a loud pipe and they "soften" the loud exhaust a bit. They round off the sharp edges of the exhaust note as it were.

Tri - I saw that one but its cast iron (ugly) and requires welding (dont want a permanent solution in case it sucks.

I have a custom snuff r not in the works...



I just need to weld that center washer to the screw and pop a hole in the pipe. A lock washer and thumb screw hold it together. As long as I turn it clockwise only, it should stay tight, we'll see. You can just see I notched the end of the screw so I had some way to tighten everything, and it lets me know where the flapper is oriented. My plan is to put it just after the header pipe. Hopefully that works, if it doesnt, I'll put it towards the end, which I guess is the more customary position.

This is the $25 emgo shorty pipe I'm using (Pipe # 4 for me!):


It has internal baffling, but basically is a straight open 1" pipe though the center, so I'm guessing it will be quite loud, but I'm hoping it has some of the flavor of the EFI pipe, just louder (my goal). The muffled section is about a foot long. One nice thing about this pipe is that it has a removable baffle, so with that functionality and the snuffrnot it should be fun to tune for back pressure (power) and sound.

I've attached three washers here, but my guess is that I may only need the one center one. When the washers are in the pipe at 90deg, there is about 1/4" clearance around the edges for exhausts gases to pass by.

I took my new bike on its first trip this weekend:  Austin to Houston and back; for the big accordion concert..  About 170 miles each way.  When we drive this in a car, its 3 hours on the road.  It was twice that on the C5, since I avoided the interstate.  Plus I needed rest stops, since it was very hot, and when I stopped for gumbo for lunch, there materialized a ferocious hail storm, and I had to wait it out.  Especially time consuming was driving in and out of Houston on surface streets.  I loved the way the bike handled on 2 lane roads.  But it was frankly very tiring keeping up with high speed traffic on the 4 lane roads, which in Texas are 70 mph.  I don’ think I would do this again – it was too arduous in return for the couple of hours pleasant riding.  I did take one section on a gravel county road.  The bike felt fine.
